GA LVAINIC- BATTERY.

SPECIFICATION formingpart of Letters Patent No. 291,871 dated January 115, '1884.

Application filed March 31, 1683. (No modelh d To all whom, it may concern:

Be it known that I, HORATIO J. BREWER, of the city, county, and State of New York, have invented a new and useful Improvement in Galvanic Batteries, of which the fol- I lowing is a full, true, and exact description,

reference being had to the accompanying drawings.

This invention-relates to an improvement upon the battery patented to G. L. Leclanch November 16, 1880, and numbered 234,413; and it consists in providing a jar of a peculiar shape, by means of which the cover may be readily sealedin the jar, by means of which likewise the zinc is automatically prevented from coming in contact with the electro-negative element.

My invention will be readily understood from the accompanying drawings, in which,

Figure 1 represents a section showing the parts in position; Fig. 2, a slight modification of the upper part of the cup.

A represents a glass cup or receiver; B, the

cover. In this is suspended the electro-negative element E and the zinc O. The jar is of a peculiar shape,.'swelling outward at the bottom, allowing the zinc O to project away from the electro-negative element, and at thesame time enabling alarger supply of liquid to be contained in a vessel having a given opening at the top. The cover B is preferably made upper end'of the cell is prevented from flowing into the cell beneath and perfect seal.

In the form shownin and forms a secure Fig. 1 the cup F is provided with flntings G to firmly hold the paraifine in place. In Fig. 2.the'cup F is curved inwardly at the top, serving to pre-:

The hole vent the withdrawal of the cover. cut in the cover B is cut on an angle with the axis of the cell, so as to cause the rod Cto project away from the electro-negative elements and sealing" them-in ment'E, which it is allowed to do by reason of the peculiar shape of the glass cell.

It is obvious .that in certain cases the shape of the glass cell may be varied and its sides may be parallel without detracting from the value of my invention-as regardsthe parafline seal. 2

What I claim as my invention, and desire to secure by Letters Patent, is

1. A cell for galvanic batteries, which con-- sists of a vessel decreasing in sizefrom the bottom upward, and then increasing in size,- forming a lip for the cover to rest on, and then again decreasing in size, thereby ena-' bling the cover to be locked in position .by a 7 seal, substantially as described.

2. The battery-cell A, decreasing in size from the bottom upward, and provided with the shoulder M, and with cup-shaped recess Ffor holding a parafline seal, in combination with said paraifine seal and with a cover locked in such recess thereby, substantially as described.

3. A galvanic cell'consisting of the cup A, provided with shoulder M, coverB. in which the elements E 00f the batteryare suspended,

and the parafline seal D, surrounding said eleposition, substantially as described. I

4. The combination of. the cell A, cover B, provided with perforation N, cut at an angle to the axis of the cell, and zinc 0, held away from the electro-negative element by reason of saidhole or perforation, thereby preventing accidental contact between the zinc. and the carbon by reason of l the proximityof the 8 5 free end of the zinc to the carbon, substantially as described.

5. A cell for galvanic batteries, which consists of a vessel provided at its upper extremity with a shoulder formed of the mate- 9o rial of the cell, and projecting inward to support the battery-cover and to permit thesame to be sealed by a parafline or equivalent seal set above the cover, substantiallyas described.
